Universe is ever-changing. There is no static philosophy. Everything is in the process of becoming something else. Every second, there are millions and trillions of changes happening in the atmosphere / around us. There's no stand for perfection when something is moving or changing. (There are somany interpretation for the word perfection. Don't get confused. It is different in case of individuals ordinary life / work life.) Under the law of universe perfection is void. Many of us are not aware of it because we are closely connected with the past and present moments. We simply don't know what future looks like. We may not be observing what's happening around us. We must live our lives acknowledging this and initiate change on a regular basis, thus putting ourselves in harmony and rhythm with this process. If there isn't change, there is no growth. With change and growth comes the need for balance. Change is the law, only quality of the universe, rest are the properties of change. Embrace the change.
